Al Pacino — ‘Dick Tracy’ Then and Now

Then: Pacino gobbled scenery and quoted Nietzsche as sneaky crime boss Alphonse "Big Boy" Caprice. Pacino was already a Hollywood legend because of his award-winning turns in movies such as 'The Godfather,' 'Serpico' and 'Dog Day Afternoon.' The hits kept coming after 'Dick Tracy' for Pacino, who spent the '90s starring in films like 'Scent of a Woman,' 'Heat' and 'Donnie Brasco.'

Now: Pacino is slated to appear with fellow acting vets Christopher Walken and Alan Arkin in the upcoming crime comedy 'Stand Up Guys.' The Oscar and Tony winner (he's currently on Broadway in 'Glengarry Glen Ross') will also don multiple wigs to portray Phil Spector in a HBO biopic on the murderous record producer.
